0F ONE-HALF TO FIDEL TOOTH-BRUSH.

Speeication of Letters Patent.

To all whom 'it may concern:

Be it known that I, JOSEPH ORTHWEIN, a citizen of the United States,residing at Sulfern, in the county of Rockland and State of New `York,have invented a new and useful Improvementpin a Tooth-Brush, of whichthe following is a specification.

This invention relates to tooth brushes, theobject being to provide atooth brush with a hollow hand-le adapted to contain a rubber tube forholding the liquid or paste, so that by squeezing the same, the liquidor paste therein will be forced on to the bristles of the, brush,-through passagesy `rformed therein.v

Another object of my invention is to provide a brush which isexceedingly simple -and cheap in construction, and one which isespecially adapted to be used by traveling people, whereby a personhaving vone of these brushes'will .not be lcompelled to carry a bottleof liquid or paste, as the paste is held within the handle in such amanner that it will not leak out.

A still further object of the invention is to provide a tooth brushwhich is exceedlngly simple and cheap in construction and one in whichthe parts are so connected, that the same can be readily 4disconnectedin order to thoroughly clean the same.

A still further object of the invention is to provide a brush which isformed of a hollow handle having oppositely disposed openings throughwhich the fingers can eX- tend for squeezing the liquid; containing tubetherein, whereby the liquid will be forced out of the tube into apassage formed in the'head of the brush from which it is lcd' throughpassages on to the bristles, whereby the amount of liquidfed onto thebristles can be readily controlled.

With these objects in view, the invention consists in the novelvfeatures of construction, combination and arrangement of parts,hereinafter fully described and pointed out in the claim.

In the drawing forming a part of this specification: Figure l is a sideelevation of my improved tooth brush. Fig. 2 is a longitudinal verticalsection through the same. Fig. 3 is a transverse section through thehandle, and Fig. 4 is a detail View of the rubber tube.

In carrying out my invention 'I emplov,

a; hollow handle A, formed of any suitable lmaterial having oppositelydisposed finger -tube B having an annular rib or enlargement B at 1tsopen end, adapted to fit against the shoulder of the handle, and to beclamped tightly by the threaded neck C of a head C, which is'screwedinto the handle, so as to form a liquid tight joint.

The head C is providedf with a threaded opening C2, in which is secureda threaded neck 'D' of a brushh'ead D which is provided with bristles E,and a longitudinal passage .F having branch passages F', extending outbetween the bristles, through whichthe liquid or paste contained withinthe rubbertube is adapted to be forced by compressing the tube withinthe handl By constructing a brush in this manner the parts can bereadily assembled, or disconnected, and by placing liquid or pastewithin the rubber tube and screwing the head down tightly, the tubewillbe locked in thehandle, in such a manner that when compressed by thelingers, inserted through the opening, the liquid therein will be forcedgradually out on to the bristles. l

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is: n
